Barlovento, Santa Cruz De Tenerife
Barlovento (Spanish for windward) is a municipality in the northern part of the island of La Palma, one of the Canary Islands, and a part of the province of Santa Cruz de Tenerife. Barlovento is on the main highway which encircles the island. The land rises steeply from a small coastal plain, to the rim of the Caldera de Taburiente at Pico de la Cruz (2,350m) The majority of the municipality is rural, with the only town being Barlovento, where the ayuntamiento (municipal office) is, at 548m above sea level. Being in the cloudier North East of the island, with a short, rocky, coastline, there is less tourism than other municipalities, although there are a number of ''casas rurales'' for rent. There is, however, a large recreation zone and campsite at the ''Laguna de Barlovento'', an artificial reservoir, which is the largest area of freshwater on the island. There are also saltwater bathing pools, the ''Piscina Fajana'', with a restaurant and other facilities at Punta del Corcho, ...

Urticaceae
The Urticaceae are a family, the nettle family, of flowering plants. The family name comes from the genus ''Urtica''. The Urticaceae include a number of well-known and useful plants, including nettles in the genus ''Urtica'', ramie (''Boehmeria nivea''), māmaki ('' Pipturus albidus''), and ajlai ('' Debregeasia saeneb''). The family includes about 2,625 species, grouped into 53 genera according to the database of the Royal Botanic Gardens, Kew and Christenhusz and Byng (2016). The largest genera are '' Pilea'' (500 to 715 species), '' Elatostema'' (300 species), ''Urtica'' (80 species), and '' Cecropia'' (75 species). '' Cecropia'' contains many myrmecophytes. Urticaceae species can be found worldwide, apart from the polar regions. Description Urticaceae species can be shrubs (e.g. '' Pilea''), lianas, herbs (e.g. ''Urtica'', '' Parietaria''), or, rarely, trees ('' Dendrocnide'', '' Cecropia''). Their leaves are usually entire and bear stipules. Urticating (stinging) hai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achenes
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruits
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seedling
A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown ab ...

Gran Canaria
Gran Canaria (, ; ), also Grand Canary Island, is the third-largest and second-most-populous island of the Canary Islands, an archipelago off the Atlantic coast of Northwest Africa which is part of Spain. the island had a population of that constitutes approximately 40% of the population of the archipelago. Las Palmas de Gran Canaria, the capital of the island, is the biggest city of the Canary Islands and the ninth of Spain. Gran Canaria is located in the Atlantic Ocean in a region known as Macaronesia about off the northwestern coast of Africa and about from Europe. With an area of km2 ( sq. mi) and an altitude of at Morro de la Agujereada, Gran Canaria is the third largest island of the archipelago in both area and altitude. Gran Canaria is also the third most populated island in Spain. History In antiquity, Gran Canaria was populated by the North African Canarii, who may have arrived as early as 500 BC. In the medieval period, after over a century of European incur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Hierro
El Hierro, nicknamed ''Isla del Meridiano'' (the "Meridian Island"), is the second-smallest and farthest-south and -west of the Canary Islands (an autonomous community of Spain), in the Atlantic Ocean off the coast of Africa, with a population of 10,968 (2019). Its capital is Valverde. At , it is the second-smallest of the eight main islands of the Canaries. Name The name ''El Hierro'', although spelled like the Spanish word for 'iron', is not related to that word. The ''H'' in the name of the metal is derived from the ''F'' of Latin ''ferrum'' (compare ''higo'' for 'fig'), a phonetic mutation that was complete by the end of the Middle Ages. The confusion with the name of the metal had effects on the international naming of the island. As early as the 16th century, maps and texts called the island after the word for 'iron' in other languages: Portuguese ''Ferro'', French ''l'île de Fer'', and Latin '' Insula Ferri''. Nevertheless, the origin of the name ''ero'' or ''er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roque De Agando
Roque de Agando (commonly called Roque Agando) is a prominent rock formation on the island of La Gomera in the Canary Islands. It is one of La Gomera's most striking features and is frequently used as a symbol for the island. Roque Agando is the most prominent of a group of volcanic plugs called simply ''Los Roques'', near the centre of the island. The others are named Roque Ojila and Roque Zarcita, and sometimes Roque Carmona and Roque Las Lajas are also included. It rises directly above the main road between the island's capital San Sebastián and Garajonay National Park in the centre, which makes it a popular tourist sight. The summit is not accessible by foot. During the 20th century, some easy rock-climbing routes were established on the peak, but climbing is now banned there, and hiking is restricted to established paths in its vicinity, as it forms part of a protected area. Remains of the indigenous Guanche sacrificial shrines have been found on the summit. These were in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Gomera
La Gomera () is one of Spain's Canary Islands, located in the Atlantic Ocean off the coast of Africa. With an area of , it is the third smallest of the eight main islands of this archipelago. It belongs to the province of Santa Cruz de Tenerife. La Gomera is the third least populous of the eight main Canary Islands with 22,426 inhabitants.

La Palma
La Palma (, ), also known as ''La isla bonita'' () and officially San Miguel de La Palma, is the most north-westerly island of the Canary Islands, Spain. La Palma has an area of making it the fifth largest of the eight main Canary Islands. The total population at the end of 2020 was 85,840, of which 15,716 lived in the capital, Santa Cruz de La Palma and about 20,467 in Los Llanos de Aridane. Its highest mountain is the Roque de los Muchachos, at , being second among the peaks of the Canaries only to the peaks of the Teide massif on Tenerife. In 1815, the German geologist Leopold von Buch visited the Canary Islands. It was as a result of his visit to Tenerife, where he visited the Las Cañadas caldera, and then later to La Palma, where he visited the Taburiente caldera, that the Spanish word for cauldron or large cooking pot – "caldera" – was introduced into the geological vocabulary. In the center of the island is the Caldera de Taburiente National Park; one of four nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acuminate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
